Ross & Henderson’s sentinel (JAMA 1980) paper on the strong relationship between long term oral premarin total dose and breast cancer was largely ignored: that with cumulative premarin dose >1,500 mg (ie 7yrs) the breast cancer risk was estimated to be 2.5 in women with ovaries (vs 0,7 sans ovaries); the risk ratio for a high cumulative dose (ie after about 15years, >3mg premarin) rose to 5.7 relative to nonusers with normal breasts.
But at the same time, Finnish papers in Maturitas showed why, because of non-physiological high E1>E2 even on oral E2, systemic ERT is preferred:
Punnonen R ea: (in E2V 2mg/d & the Renin-Aldost system: 1980:2:91-4) that “on oral E2v the E2 levels rose to normal and (unlike on oral premarin, EE2) caused no rise In BP, aldost, renin; they thus preferred such natural ERT which does not activate the biliary, RAS renin-angiotensin system, and thrombosis”;
but Heinonen PK et al (1982:4: 273-6 Estrogen levels on oral E2) showed that on E2v 4mg/d orally, blood E2 rose 5X and E1 rose 25X; so they recommended avoiding oral ERT.
Thus the Womens’ Health Initiative confirmed three facts:
1. starting OHT well after age 60yrs and continuing even modest dose cyclic (premarin 0.625mg plus MPA 5mg) does more harm than good; THIS SAYS NOTHING ABOUT APPROPRIATE PHYSIOLOGICAL BALANCED COMBINED PARENTERAL TESTOSTERONE-PROGESTERONE-ESTRADIOL HRT FROM ANY POSTMENOPAUSAL AGE HAVING ANY LIFELONG RISKS WHATSOEVER.
2. starting the same OHT regime soon after menopause - especially premarin alone- reduces all major diseases and mortality by about a third, except for rare cases of deep vein thrombosis and cholelithiasis; this outcome was confirmed in the 9year RCT in Finland (Heikkinen ea 2006) in which women on oral estradiol 1mg/d +- MPA 2.5mg from menopause had zero major adverse events. BUT THIS SPEAKS ONLY FOR AT MOST THE 9 YEARS THAT THESE WOMEN WERE IN THE TRIALS.
There are so far some seven major functional types of steroid hormones in humans: calciferols; androgens; estrogens; progestins; glucocorticoids; mineralocorticoids; and endogenous digitalis- natriuretic hormone (eg Goldstein 2006, Weidemann 2005; Kurup ea 2003) .
Apart from gender-reproduction-childhood growth promotion (ie androgens, estrogens & progestins), their actions fall into many other systemic classes; which in conventional “replacement” doses the literature and experience suggests may be compared as follows:

The active hydroxycalciferols are in a sense exocrine ie are produced from ingested vitamin D3 and cholesterol in the skin and kidneys, not from dedicated endocrine glands; but while their synthesis needs no more than an hour of sunlight a week in sunny climates, and modest kidney function, calciferol deficiency is increasingly recognized in those who take little dairy products, and little sunshine. Thus the pituitary, skin, parathyroids, adrenals and gonads are the primary endocrine glands of growth.
The other steroid hormones (like the other major anabolic hormones- insulin and human growth hormone HGH) are endocrine ie are vulnerable to both intrinsic endocrine failure (Hypothalamic-Pituitary-Adrenal- pancreatic-Gonadal ), and to endocrine gland decrease and blockage by infections, cancer, major stress, auto-antibodies or direct trauma.
All these anabolic hormones if swallowed are destroyed by digestion/ 1st-pass hepatic metabolism; thus to achieve the same systemic effect, comparative doses are reported as follows:

The vulnerability of oral steroid therapy is illustrated by oral contraception: where taking eg an oral antibiotic can compete for absorption, reducing blood SH levels so that accidental conception occurs. Similarly, a postmenopausal patient with rheumatoid arthritis, on oral (E+P HRT), reports that her analgesic requirements rise while she is on antibiotics.
One needs to go back to a standard textbook of Pharmacology of 1958, (Kranz & Carr: Pharmacological Principles of Medical Practice: Balliere, London) to find the corollary: eg “cortisone acetate implant, or im 2-5mg daily injection as replacement for Addisons’ Syndrome”: “For menopausal symptoms, combined E+TT is often employed…”; “oral synthetic estrogens (have replaced natural ones due to availability, oral form & lower cost; but) produce undesirable: nausea, cramps, migraine and male breasts. Estrogen + TT are additive, and E doses may therefore be reduced since the combination gives smoother transition: 73% of patients remain symptom free. TT 10mg imi 3 x/week may control functional uterine bleeding better than progesterone”!.
It is widely overlooked that TT is converted irreversibly by aromatase to E2 in the tissues; but giving E2 does not do the reverse – it suppresses the HPAG and TT production. Thus women need to be given TT with estrogen, but men do not need to be given estrogen - giving them TT increases their E2 levels by about 1/3. This source of E2 may not be enough for balance in women, but reduces their needed dose of administered estrogen; hence in women on a standard 20:1 TT:E2 injection combination, or on combined implants eg TT 50mg + E2 20mg/6months, the blood TT level should be monitored to check that the mean TT is in the physiological range of 1-3.5nmol/L, but the E2 level need not be above perhaps 0.1nmol/L – in fact, to avoid excess fat deposition and breast cancer stimulation, it must not , since TT is supplying E2 direct in target organs.
Hence Ginsberg J & Prevelic GM at Royal Free Medical School ( Drug Therapy & Reproductive Endocrinology: London: Arnold 1996) note that in BRCA, androgen + prednisone give good results; they advise: parenteral> oral ERT: eg E2 patch 50u/d; or Implants eg TT 50mg + 20mg E2 /6mo (= 300mcg TT + 110mcg E2/ day)..
In TOPICS IN O & G 1998: (ed Julian Bassin: Julmar Communications, Jbg 4th Ed 1998: sponsored by all the RSA gyne Drug Suppliers): Schnitzler CM wrote that “ERT should be given for life, from as early as possible, but even from 80yrs; the elderly not exposed to the sun needing >2000u vit D/day. Sonnendeker on HRT wrote that oral HRT raises both coagulation & renin substrates acutely; EE2 should not be used for ERT; thus he prefers oral ERT except if coagulopathy, liver/biliary/ triglyceride/ or vascular headache problems, when he uses non-oral ERT. Indications for androgens are: poor libido; persistent tiredness & OP; preferring the 25mg TT pellet to oral androgens or imi esters”.
Finally, the physiological logic of parenteral (as opposed to oral) HRT- in this case sex hormone replacement) was already well recognized and marketed over 60 years ago – even in South Africa- in eg the handbook Sex Endocrinology (Schering, New Jersey, 1944) which recommended and listed creams, injections and implants as well as tablets.
William Masters and colleagues followed this up with the first apparent RCT of HRT published in 1953, who showing in a 13month titration RCT that biweekly ie shortacting esters imi TT 20mg + E2 1mg (= T ~2.8mg/d + E2 ~0.14mg/d, ie a ratio of 20:1 to 22:1 – as in Schering’s Primodian Depot or Organon’s Mixogen) restored 70% of geriatric women in their mid70s to selfcare; allowing the nursing staff on the unit to be halved. Overall the women had ~one brief menstrual bleed after about 5weeks, thereafter on follow-up biopsy all maintained endometrial atrophy. Some needed initial T:E dose titration (between eg 30:1 to 15:1) for individual variation in response. As a result both Schering and Organon to this day sell this preparation as a 100mg TT ester + 5mg estradiol ester ial, to be given as desired every 3 – 6 weeks.
We have found for the past ~10 years that, just as hypogonadal men do optimally on about 200mg depotrone subcutaneously sc every fortnight (= 10mg TT a day), women do well on Masters’ 20:1 TT:E2 hormone ratio, the optimal regime being on average 0.2ml 20mg of hormones by domestic subcutaneous selfinjection every 2 weeks ie TT 1mg/day and E2 0.05mg/day, – the average resultant blood levels being TT round 2.5nmol/L - but of course the testosterone itself delivering far more estradiol extra- and intracellularly.
With this regime we have never seen a breakthrough bleed in postmenopausal women, for the simple reason that follow-up endometrial ultrasound uniformly shows endometrial atrophy. We have also never seen increasing changes on follow-up screening mammography since it is common cause that testosterone suppresses female glandular breast proliferation.
These results with arenteral HRT have been abundantly confirmed in women followed for up to 40years on parenteral HRT by leading menopause clinics such as Greenblat & Ganbrell(Augusta); Gelfand(Montreal); Schiff(Boston), Buster(Houston), Notelovitz (Florida), Vliet(Tucson), Lichten(Michigan), Shippen(Philadelphia), Karpas(Atlanta); Schleyer-Saunders, Whitehead and Studd(London UK); Tvedegard Moller & Hansen(Copenhagen); Burger & Davis, Zhou & Dimitrikakis (Australia); and our Cape Town group under Davey;
and
most important of all: since longterm trials beyond the necessary critical 20 years will never be carried out in humans due to the cost, the results of primate studies by Thomas Clarkson ea at Wake Forrest University showing that starting even oral premarin at castration in young female monkeys and continuing it for the human equivalent of 15 years blocked onset of atheromatous disease ; but premarin alone or with MPA produced breast proliferation; but like endometrial proliferation, this was suppressed by testosterone replacement.
The greatest myth (if not drug industry hoax) of the past 30 years may be the claim that postmenopausal women (or for that matter women needing contraception) need a patent estrogen and a synthetic progestin for endometrial and breast protection and contraception; when it was shown decades ago that depot estradiol plus depot progesterone- or better still, depot estradiol plus depot testosterone plus depot progesterone - do best for both contraception and HRT and all-system protection against all the degenerative diseases of aging.
The fevent hope and effort of the patent designer drug industry is that they can buy off enough practitioners, academics, researchers, Regulators and politicians so that the widespread avilability, low cost - and massive all-disease prevention- of such natural supplements as human hormones as well as the dozens of other proven biologicals including vitamins and mineral is never appreciated and utiized. They cannot curb their insatiable lust for immediate endless profits no matter how much suffering it causes - disaster capitalsm- by recognizing that if they now promote such safe cheap proven panaceas to both the poor and the prosperous consumers, they will extend healthspan by decades, producing far more survivors who will later rather than sooner still need/want to buy their designer products.
